A local library manager randomly surveys 80 patrons about the type of book they borrow when they visit the library the manager finds that three patrons borrow novels if the local library has $345 patrons approximately how many of them borrow novels when they visit the library around your answer to the nearest whole number
Based on the survey data, 3 out of 80 patrons borrow novels when they visit the library.
To estimate the number of patrons who borrow novels when the library has 345 patrons, we can set up a proportion:
3 novels out of 80 patrons = x novels out of 345 patrons
(3/80) = (x/345)
Cross multiplying:
80x = 3 * 345
80x = 1035
x = 1035 / 80
x ≈ 12.94
Therefore, approximately 13 patrons borrow novels when the library has 345 patrons.
